One time I was preparing for a chess game in a tournament and I knew my oponent was a certain master. So I searched his games online to see what opening (series of moves in the beginning of the game) I could use on him. When someone asked me what I was going to do I said "Don't worry I'm gonna find an opening for his ass." (no homo) Right after I finished saying that the next words that came out of my mouth were "oh no"
